Windows Update Error 80072efd. (windowsupdate_80072efd)

Hi, I have been having numerous problems with the Windows Update Error 80072efd. I have tried every solution to no avail.
Initially I was getting the “Windows Update error 80070002”. So I followed the solution as proposed by Microsoft. Namely I stopped the Windows Update service, deleted temporary update files, and restarted the Windows Update service. But then when restarting
Windows Update I ended up receiving this lovely new error called WindowsUpdate_80072EFD. I tried restoring the computer to a time before I had received any of these problems, but I still got this error. I
tried to solve it by turning off the firewall and by waiting 30 minutes before updating again, but to no avail. Then I added these sites as trusted sites in the security of internet explorer

http://*.update.microsoft.com

https://*.update.microsoft.com

http://download.windowsupdate.com

I then created a new rule in the advanced windows firewall that allows the program: wuapp.
In the basic windows firewall, i added wuapp as an exception. Again, to no avail. So I clicked on the Start menu, selected Run and type the following: regsvr32 Dssenh.dll Gpkcsp.dll Slbcsp.dll Sccbase.dll This gave me a
window that said: "The module "Gpkcsp.dll" failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .dll files. The specified module could not be found."I
then uninstalled the anti-virus (because I couldn’t disable it) and still received the same error. I thenadded these sites as trusted sites in the security of internet explorer

§http://update.microsoft.com

§http://windowsupdate.microsoft.com
But I still received the error. I read somewhere to run the Update for Background Intelligent Transfer Service (BITS) 2.0 and WinHTTP 5.1 (KB842773), but no such updates exist for vista. I then
created a coupld new rules for windows firewall: outbound rule for a TCP Port of the number 65,55,184,125,
an inbound rule for a TCP Port of the number 65,55,184,125,
an outbound rule for a UDP Port of the number 65,55,184,125, and
an outbound rule for a UDP Port of the number 65,55,184,125. Again, to no avail. I read that I should disable any software accelerators, but to the best of my knowledge I don't actually have any. Any help would be appreciated.
